IMPROVEMENT IN OULTIVATORS.

To ALL wHoM 1T MAY couches:

Beit known that I, JOHN W. DoUD, of Forestvillo, in the county of Delaware, and Statie of Iowa, have invented a new and useful Improvement in Cultivators; and I do hereby declare that the following is a full, clear, and exact description thereof, whichv will enable others skilled in theart to make and use the same, ref erence boing had to the accompanying drawings,for ming part of this specification.

Figure lis atop view of my improved cultivato'r.

'Figure 2 is aside view of the same, partly in section, through the line :l: x, iig. l.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish a simple, substantial, durable, arid cheap cultivator for putting in all kinds of grain sown broadcast, and for prepa-ring the ground for winternvheat, which shall be so constructed as to economize time, labor, and seed in putting in the grain, the machine destroying the weeds and covering the grain uniformly, so that it can allcome up; and it consists in the construction,combination, and arrangement of the various parts, as hereinafter more fully described.

A are wheels, and B is the axle, with which the other parts of the'cultivator are connected in the manner hereinafter-described. C is the frame of the cultivator, consisting of two sidel bars, e, and two end bars, c2, securely framed to each other..I The frame is strengthened by X-shaped braces, D, as shown in iig. 1. E is a beam, crossing the frame e diagonally from corner to corner, and securely attached to the said frame. F are the plough-standards, to the lower ends of which the shovels or ploughs G are attached, and the upper rends of which are attached to tho diagonal beam E. The standards F are strengthened by brace-rods, H, running from the lower parts of said'standards to the brace-bar D that runs parallel with thesaid beam E. The number of standardsland ploughsused should vary with the size of the cultivator. p I is the tongue, which is attached to the forward end of the frame C.\ To theaxle B are attached two inclined bars, J, meeting each other at an angle over thefrear part of the tongue I, with which they are connected with a jointed or linlc connection, K, as shown in Iig. 2. L are chains, the lower ends of which are attached to the forward corners of the frame O, andk the upper endsof which are hooked upon hooks attached to the ends of the erossbar M, secured to the inclined bars J. N is a lever, pivoted to supports O, attached to the central part of the axle B, and to the rear end of which is attached a hook, upon which hooks a-short chain, P, the lower end of which is attached to the central part ofn the bail or bariR, the ends of which are attached to the side bars of the frame C, so that by lowering the forward end ofthelever N, the ploughs may be raised from thc ground for convenience in turning or in passing over obstructions. S is a lever, the rear end of which is pivoted tothe side bar cl of the frame C, which passes through a keeper attached to the axle B, and to the forward end of which is pivoted one end of the lever T, which is pivoted'to one of the inclined bars J, and its other end extends inward into such a position as to be easily reached and operated by the driverfrom his seat.

By depressing the inner end of the lever T,`the rear ond ofthe lever S will be depressed so as to bear down upon the frame O, and force the ploughs farther-into the ground. The levers S and T are only necessary when using the machine 4upon hard ground. By shortening the chains and P, the frame C may be suspended close to the 'axle B, so that the machine may be conveniently moved any desired distance.

U are downwardly-projecting arms, attached to the axle B,Vupon each side of the frame C, to limit the side movements of said frame. V are adjustable gauge-wheels, attached to the front and rear ends of the frame O, to regulate the depth at which the ploughs run in the ground.

I claim as new, and desire to secure by Letters Patent- 1. The combination of the frame C, strengthening-braces D, and diagonal plough-beam E, to which the i standards F cf the'iploughs G are attached, with each other, the said parts being constructed and arranged sub- Aherein shown and described, and for. the purpose set forth.

stantially as herein shownand described, and for the purpose set forth.

2. Connecting the axle B to the tongue I of the frame C- by the inclined bars J, and jointed or link connectionl K, substantially as herein shown and described. l .K

3. The combinationlof the cross-bar M and adjustablechains L with the inclined bars J and frame C, substantially as herein shown and described, and for the purpose set forth.I

v 4. The combination ofthe lever N, chain l), and bail or bar R with the frame C and axle B, substantially as herein shown and described, and for the purpose set forth.

5. The combination of the levers S and T with the frame C, axle B, and inclined bar J, substantially as IJOHN w. DoUD.
